Critical minerals are used in a range of defense, autos, space travel, batteries and other equipment, but the US relies on China and other nations for most of its supply.

President Donald Trump launched a probe into the need for tariffs on critical minerals, the latest action in an expanding trade war that has targeted key sectors of the global economy.

The order, which Trump signed on Tuesday, calls for the commerce secretary to initiate a Section 232 investigation under the Trade Expansion Act of 1962 to “evaluate the impact of imports of these materials on America’s security and resilience,” according to a White House fact sheet.

If the secretary finds that imports of critical minerals threaten to “impair national security and the President decides to impose tariffs,” those levies would take the place of current so-called reciprocal duties Trump announced earlier this month on US trading partners.

The order covers critical minerals, including rare earth elements, casting them as critical “building blocks of our defense industrial base” and crucial to building jet engines, missile guidance systems, advanced computers, as well as radar, optics and communications equipment. The order also covers uranium as well as processed critical minerals and derivative products.
